Stop losing money on accidental discounts. Protect your margins with ease

Ever run a 20% off Black Friday sale, only to realise a customer used it on a premium product with a 10% margin? Margin Defender is your failsafe!

Margin Defender prevents you from accidentally discounting premium items that should never be on sale. Simply tag specific products as "protected," and this app will block checkout if any discount code is applied while those items are in the cart.

Designed to be the simplest, most efficient way to protect your bottom line from unintended discounts.
